I live 7 hours away from my boyfriend. He works a lot and doesn't have a lot of time to talk throughout the day. I like to leave him sweet messages but I'm running out. Can you give me some ideas so I won't be repetetive?

Think of the first message u left him,he probably won't remember that u used that one already.then use the one that means the most to u or him. A simply message like a kiss or a smile with a kiss.
